A linear display device for economic management

Abstract

The invention provides a linear display device for economic management, which relates to the field of teaching appliances. The economic management linear display device includes a display board, the bottom of the display board is fixedly connected with a fixed bar, one side of the fixed bar is provided with a moving sleeve, the inside of the moving sleeve is fixedly connected with a fixed shaft, the inside of the fixed shaft is provided with a threaded hole, and the top of the mobile sleeve is provided with a There is a third groove, and a second sliding groove is provided at the bottom of the moving sleeve. A coil spring is fixedly connected to the inside of the second sliding groove. The economical management linear display device can effectively fix the first magnetic block at each vertex of the data map to be displayed by moving the sleeve and sliding on the display board, and display the data through the first rotating block and the wire inside the fixed shaft The direction of the line does not need to be drawn manually, which avoids the problems of not straight line segments and unequal spacing caused by manually drawing line segments.

Description

technical field [0001] The invention relates to the technical field of teaching appliances, in particular to a linear display device for economic management. Background technique [0002] In the process of teaching economics and management, most teachers need to carry out some statistics and trend analysis of data. In order to avoid problems that are difficult for students to understand by telling students in oral form, many teachers will use the method of drawing straight lines. Data graphs such as charts and fan charts are used to display and explain in detail the statistics and trend analysis of data. [0003] Most of the traditional data map drawing methods are teachers repeatedly drawing manually on the blackboard. In general manual drawing, there will be problems such as non-straight line segments, unequal spacing, and inability to accurately draw within the required data range. Economic management is It is a very rigorous profession that requires high data accuracy. ...

Problems solved by technology

[0003] Most of the traditional data map drawing methods are teachers repeatedly drawing manually on the blackboard. In general manual drawing, there will be problems such as non-straight line segments, unequal spacing, and inability to accurately draw within the required data range. Economic management is It is a very rigorous profession that requires high data accuracy. Most teachers will use tools such as rulers, triangles, and compasses to draw data graphs. Repeated operations and tool replacement bring physical burdens to the operators. And it will delay the effective teaching time in the classroom and delay the learning time of students
